This study evaluated the effectiveness of nasoseptal cartilage for repairing traumatic orbital floor defects.
Autogenous septal cartilage was used in 20 patients. They were evaluated for the presence or absence of diplopia, enophthalmus, infraorbital nerve paresthesia, and ocular motility disorders. Surgical indications for orbital exploration included entrapment of orbital tissues, large orbital defect (greater than 50% of the orbital floor or more than 8 mm), or orbital floor defects with involvement of other zygomaticofrontal complex fractures.
All patients were successfully treated by restoration of the orbital wall continuity. Follow-up at 1 week to 6 months showed 1 patient with postoperative enophthalmos and 1 patient with lower lid edema. There were no donor site and graft infections or graft extrusion.
Nasal septal cartilage is a readily accessible autogenous tissue that should be considered when an autogenous graft is needed for orbital floor defect reconstruction.
本研究评估鼻中隔软骨修复外伤性眶底缺损的有效性。
20例患者使用了自体鼻中隔软骨。评估患者有无复视、眼球内陷、眶下神经感觉异常及眼球运动障碍。眼眶探查的手术指征包括眼眶组织嵌顿、大的眼眶缺损（大于眶底的50%或超过8毫米）或伴有其他颧额复合体骨折的眶底缺损。
所有患者均通过恢复眶壁连续性成功治疗。1周至6个月的随访显示，1例患者术后出现眼球内陷，1例患者出现下睑水肿。没有供区和移植物感染或移植物挤出情况。
鼻中隔软骨是一种易于获取的自体组织，在需要自体移植物进行眶底缺损重建时应予以考虑。
